Description of Related Art

Sleep is important and plays a vital role in good health and well-being. Sleep can affect mental health, physical health, quality of life, and safety. It affects the way individuals act and perform when they are awake. The dangers of sleep deficiency can include physical harm, such as causing accidents while operating vehicles or machinery, or, over time, can cause chronic health problems. Studies have also shown that sleep helps significantly in the healing process. However, in many settings, such as hospitals and nursing homes, individuals who are most in need of sleep are unable to obtain quality sleep. This is due to the numerous disturbances that occur in such settings, such as hospital alarms, medication administration, vital measurements, and other disturbances that occur near constant to those trying to recover. This is sometimes due to emergency scenarios, but often it occurs because personnel tasked with taking care of individuals in such situations often do not consider a patient's sleep schedule and the importance of quality sleep. At least one study has shown that in a hospital setting, over the course of an entire week, most patients never obtain a full sleep cycle, which is typically considered to be 90 minutes.

Devices exist, which are capable of monitoring sleep, such as those disclosed in U.S. Pat. No. 8,512,221 to Kaplan et al., but no such systems have been previously used in combination with other components so as to convey permitted or redistricted disturbance events or protocols to be administered to a subject so as to allow the healing properties of sleep to inure to the benefit of a subject or patient.

DESCRIPTION OF THE INVENTION

With reference to FIG. 1, the system and methods of the presently described embodiment generally may require the following: collecting real time sleep data, determining sleep status, such as the amount of time a subject has been asleep, generating a sleep disturbance priority message, and then administering the protocol dictated by the determined sleep status. The protocol could take the form of performing any number of procedures on a subject individual. As discussed herein, such protocols refer to what the present disclosure will refer to generally as disturbance events. Disturbance events are simply actions or procedures administered to or for a subject, for example, a patient in a hospital setting. Examples of such actions may include taking vital measurements, administering medication, flushing IV fluids, or changing sheets. The systems and methods described herein are described generally in reference to a patient-hospital setting but may take the form of any setting wherein a subject may require periods of continuous and prolonged sleep without disturbance.

The collection of sleep data can take many forms, and, may, for example, take the form of a sleep monitoring device. One form of a sleep monitoring device that may be used is an electroencephalography (EEG) monitor, which could monitor brain activity. An example of a monitoring device 300 that may be used according to embodiments of the present invention is shown in FIG. 7 and will be described in more detail herein below. Other potential monitoring techniques may include electromyography (EMG), peripheral arterial tone (PAT), systolic upstroke time, electrocardiography (ECG/EKG), electrooculography (EOG), oximetry, heart rate monitoring, such as heart rate variations or heart rhythm variations, actigraphy, galvanic skin response (GSR), respiratory monitoring, eye movements, temperature measurement, motion measurement, such as through accelerometers, or any other type of measurement that can be used to determine and/or measure sleep.

The functions included with box 2 of FIG. 1 generally may follow the process detailed at FIG. 2. For example, a monitoring apparatus 101, see, e.g., FIG. 3, may idle if it is determined that the subject is not connected. If the subject is connected to the monitoring device 101, as illustrated at decision point 11, the system may then make a determination of whether the subject is asleep, as indicated by decision point 12 in FIG. 2. This decision may be made at a monitoring apparatus 101, at a receiving station 110, described in more detail herein below, or elsewhere in the overall system. If the subject is asleep, the system may make a sleep status determination, such as at decision point 13. For example, the system may determine for how long the subject has been asleep, what stage of sleep the subject is presently in, or some other measurement of the length and/or quality of the subject's sleep. The example illustrated in FIG. 2 shows an embodiment of the system that uses the amount of time the subject has been asleep to determine what protocol should be used.

In the embodiment of FIG. 2, the system determines whether the subject has been asleep for a predetermined period of time t_(p). If the subject has, in fact, been asleep for the period of time t_(p), then an intermediate disturbance priority exists and disturbance events categorized as intermediate priority disturbance events are authorized to be performed. Likewise, as illustrated in FIG. 2, if the system determines that the subject has not been asleep for the predetermined period of time t_(p), then the subject is in the top disturbance priority category, wherein only disturbance events categorized as top priority disturbance events are authorized to be performed. If it is determined that the subject is awake, indicated in FIG. 2 by the “No” branch of decision point 12, then the system may determine at decision point 14 whether the subject is transitioning to sleep, such as by one or any combination of the sleep monitoring techniques described above. If it is determined that the subject is transitioning to sleep, indicated by the “Yes” branch of decision point 14, then disturbance events authorized only for the transition phase of sleep may be administered to the subject. If it is determined that the subject is not transitioning to sleep, indicated by the “No” decision branch of decision point 14, then no disturbance priority is necessary and disturbance events of all priority levels may be administered. The system then generates a disturbance priority message conveying that the particular disturbance events authorized for a particular disturbance priority are permitted to be performed on the subject.

As shown in FIG. 2, after the system has determined whether the subject has been asleep for a predetermined period of time t_(p), less than the predetermined period of time t_(p), or is awake, the system then generates a disturbance priority message for conveying the particular disturbance events that are authorized to be performed on the subject based on the determined disturbance priority, i.e., intermediate priority events (including top priority events) for an intermediate disturbance priority, top priority events for a top disturbance priority, transition disturbance events for a transition disturbance priority, and all disturbance events if the subject is awake. The disturbance priority message is then further displayed so as to convey that information to an operator, or, in the case of a hospital setting, an attendant nurse, physician, or other hospital personnel, so that the authorized protocol can be administered on the subject.

As shown in FIG. 3, an embodiment of a system 100 according to the present invention may include a sleep status monitoring apparatus 101, a receiving station 110, and a display 130. The monitoring apparatus 101 is in communication the receiving station 110, which, in turn, in is communication with the display 130. In some embodiments, the receiving station 110 and the display 130 may be integrated into a single device or they may be separate devices, which could be located remotely from each other. The monitoring apparatus 101 is connected in some manner to a subject S. The subject S may be a patient in a hospital setting, a resident of a nursing home, a volunteer for a sleep study, or a person in any other setting wherein monitoring of sleep data may be useful. In some embodiments, the system may include an optional database 120 that is accessible by the receiving station 110 and/or the monitoring apparatus 100. The database 120 may contain rules relating to certain priority events in the system. The database 120 may be located on the receiving station 110, on the monitoring apparatus 101, or anywhere else, for example, on a server or computer on a network, that is accessible to the receiving station 110 and the monitoring apparatus 101.

Referring now to FIG. 4, an embodiment of a system 200 may include a plurality of sleep status monitoring apparatuses 201 a-201 f, a plurality of receiving stations 210 a-210 h, a database 220, and a network 240. In this illustration, system 200 of FIG. 4 is depicted as a portion of a hospital floor with attending medical personnel P1 and P2, but this configuration may be used in settings wherein multiple monitoring apparatuses/receiving stations are necessary. As shown, each of the monitoring apparatuses 201 a-201 f, receiving stations 210 a-210 h, and database 220 may be in communication with the network 240. In some embodiments, the monitoring apparatuses and receiving stations may be in direct communication with each other, such as shown with respect to monitoring apparatuses 201 d-201 f and receiving stations 210 d-210 f. For example, they may be connected directly through wireless communication, such as Bluetooth®, or through direct wired connection. Alternatively, in some embodiments, the monitoring apparatuses and receiving stations may be connected over the broader network 240, such as shown with respect to monitoring apparatuses 201 a-201 c and receiving stations 210 a-210 c, 210 g, 210 h.

As illustrated, the receiving stations 210 a-210 f of FIG. 4 may positioned remotely from the monitoring apparatus directly outside patient rooms 250 a-250 f. However, the receiving stations may also be positioned remotely to even the patient rooms 250 a-250 f, such as with respect to receiving stations 210 g, 210 h. Receiving station 210 g may be located at an attendant or nurse's station 260, and may take the form of a computer having a monitor display 230 g. In this regard, multiple subjects may be monitored from a single receiving station. Receiving station 210 h may be a portable or mobile device, such as tablet computer, smart phone, or smart watch, having a display 230 h that can accompany medical personnel P1 regardless of P1's location. As illustrated in FIG. 4, receiving stations 210 b-210 f do not include a separate display, as they may optionally include an integrated display, such as on a tablet computer or smart phone. Room 250 a, on the other hand, shows an embodiment wherein the receiving station 210 a is separate from the display 230 a. In this instance, receiving station 210 a may, for example be a computer or other hardware capable of receiving and processing the data transferred from the monitoring apparatus and displaying data on the display 230 a. In such embodiments, receiving station 210 a may be positioned inside room 250 a with display 230 a outside of room 250 a. Or, as illustrated, both receiving station 210 a and display 230 a may be position directly outside of room 250 a.

As further illustrated in FIG. 4, the database 220 may be connected to the various other components of the system 200 via the network 240, such by being located on a server 225 on network 240. Alternatively, the database 220 may be located on one or more of the monitoring apparatuses 201 a-201 f or receiving stations 210 a-210 h.

Referring now to FIG. 5, which is an enlarged view of room 250 d of FIG. 4, the monitoring apparatus is connected to subject S_(d). The monitoring apparatus 201 d may take the form of an EEG monitor, such as the commercially available Z-MACHINE® from General Sleep Corporation of Euclid, Ohio or the MUSE™ from Interaxon. Of course, other techniques for monitoring the sleep of the subject S_(d) may be utilized, such as EMG, ECG/EKG, PAT, EOG, GSR, heart monitoring, respiratory monitoring, accelerometers, or other means of measuring motion, and temperature measurement. In embodiments where the monitoring apparatus 201 d takes the form of an EEG device/monitor, the apparatus measures or monitors electrical brain activity to track and/or record brain wave patterns. The monitoring apparatus 201 d may take the form of electrodes placed on the head, or elsewhere, on the subject S_(d). Alternatively, the monitoring apparatus 201 d may take the form of a headband to be worn on the head of subject S_(d), wherein the headband would include electrodes to measure electrical brain activity. The monitoring apparatus 201 d is in communication with the receiving station 210 d. The monitoring apparatus may be connected directly to receiving station 210 d, such as through the connections explained above, or through the broader network 240. The example shown in FIG. 5 shows the receiving station 210 d as having an integral display 230 d. In this instance, receiving station 201 d may take the form of a tablet computer, but may take the form of any hardware capable of receiving and processing the data transmitted from the monitoring apparatus and displaying data indicative of the data received.

In practice, the monitoring apparatus 201 d collects real-time sleep status data from the subject S_(d). For example, in the case where the monitoring apparatus 201 d takes the form of an EEG monitoring device, the monitoring apparatus could measure and collect electrical brain activity data, or, in the case where the monitoring apparatus 201 d includes accelerometer functionality, the monitoring apparatus may measure and collect movement data. The monitoring apparatus 201 d also transmits the real-time sleep status data to the remotely positioned receiving station 210 d via, as explained above, BLUETOOTH® or other wireless communication method, through a larger network, and/or a wired connection. The receiving station 210 d, upon receiving the real-time sleep status data, may process the data according to the steps illustrated in FIGS. 1-2. Accordingly, it may determine a sleep disturbance priority based at least partially on the real-time sleep status data and may generate a sleep disturbance message including data indicative of the sleep disturbance priority level. The determination of the sleep disturbance priority may take place alternatively at the monitoring apparatus 201 d as well. The receiving station may then display the sleep disturbance message on the display 230 d located remotely from the sleep status monitoring apparatus 201 d.

In some embodiments, the systems herein may incorporate a database, such as databases 120, 220. Referring to database 120 of FIG. 3, the database may be accessible by both the receiving station 110 and the monitoring apparatus 101. The database 120 may be located on either the receiving station 110 or the monitoring apparatus 101. Alternatively, as shown in FIG. 2, a database 220 may simply be accessible to the various components of the system via the overall network. The database may take the form a relational database. The database may include rules associated with what disturbance events may be administered. For example, the rules may include a priority ranking of disturbance events to be administered by an operator on the subject.

A graphic depiction of an exemplary embodiment of these rules is shown in FIG. 6. In FIG. 6 the horizontal axis represents sleep time. There are two points in time represented on the horizontal axis, t_(p) and t_(a). Time t_(p) represents a predetermined period of time, which may be a period of sleep determined to be long enough to provide a sleep benefit to the subject. For example, t_(p) may represent one sleep cycle, a particular stage of sleep, or any other period of time. In one embodiment, t_(p) may be 90 minutes. After a subject falls asleep, but before time t_(p), the rules in the database may require the system to recognize a top disturbance priority and they may restrict all disturbance events to be administered on the subject except for a small number of top priority events, which may be considered emergency events. After the time t_(p), but before time t_(a), which the time at which the subject is awake, the rules in the database may require the system to recognize an intermediate disturbance priority and they may permit intermediate disturbance events that are not emergency procedures, but that are important enough to justify disturbing the subject. The rules in this instance may also permit administration of the top priority events during this time period. After time t_(a), the system may recognize no disturbance priority is necessary, and the rules may dictate as such. The rules at this stage may also specify that all disturbance events, regardless of disturbance priority designation, may be administered. The rules would permit all disturbance events that are not categorized as intermediate or top priority to be performed, in addition to the intermediate or top priority events. These other remaining events may be categorized as low priority disturbance events. The rules may dictate that those disturbance events with no priority designation or a low priority designation would never be permitted to be performed during an intermediate disturbance priority or a top disturbance priority. FIG. 6 represents the disturbance events as a pyramid with the top priority events being at the top, the intermediate in the middle, and all remaining disturbance events at the base of the pyramid. This is because the rules may be implemented in such a way so as minimize the number of top priority events that are always required to be performed on a subject regardless of the subject's level/time of sleep, whereas the intermediate priority events that are permitted may be slightly more in number, and whereas, when the subject is awake, there are no restrictions on the number of disturbance events that may be performed. Alternatively, to be implemented on a database, these rules could be implemented on the receiving stations or monitoring apparatuses separately. For example, they could be programed into an application for an operating system, a tablet computer, smart phone, or other computing software, which is saved on such computer devices' hard drives.

Alternative rules may dictate the disturbance priority and authorized disturbance priority events based not simply on time, but on the stage of sleep or sleep cycle of the patient as opposed to or in combination with the patient's sleep time. For example, the monitoring apparatus may determine the stage of sleep, e.g., the standard stages 1-4 and REM sleep, based on the sleep data, e.g., EEG data, being recorded from the subject, and then based on the disturbance events and rules in the database make a determination as to what the disturbance priority level and/or authorized disturbance events should be. Rules may also be tailored to a particular subject depending on the subject's needs. A learning loop may also be included, wherein the monitoring apparatus or the receiving station modifies the rules applied to a particular subject. For example, the system may start with a single set of rules dictating which disturbance events may be administered on set time intervals of sleep, or on particular stages of sleep. But after administering these rules, the receiving station or monitoring apparatus may determine that a subject is not responding to or responds better to a particular disturbance event during a particular stage of sleep or time interval. This determination may be accomplished through manual entry of information by an operator or by direct measurement of the subject. After acquiring this information, the system may then adjust the rules as applied to the subject to modify the disturbance priority designation of one or more disturbance events. In other examples, a system, such as system 200 of FIG. 4, having multiple nodes may implement a learning loop utilizing information gathered from one or multiple nodes so as to adjust the rules to a standard across all subjects.

Non-limiting examples of disturbance events may be as follows: vital sign measurement, patient bathing/oral hygiene, toileting, turning and positions, blood sugar testing, blood draws, VTE prophylaxis, specimen collection, oxygen administration, respiratory treatments, medication administration, IV medication administration, new patient assessment paperwork, new patient assessment MD, X-rays, intake and output, weight and/or height measurements. In some embodiments, patient assessment paperwork, X-rays, weight and/or height measurements, or intake and output, may be examples of a low priority disturbance event, whereas medication administration, turning and positions, toileting, and vital sign measurement may be examples of intermediate priority disturbance events, and whereas oxygen administration and respiratory treatments may be examples of top priority disturbance events. Any combination of procedures or events may be combined according the needs of a particular application.

Referring now to FIG. 7, an embodiment of a system 300 according to the present invention may include a receiving station 310 and a monitoring apparatus 301 that may be wirelessly connected to one another. The monitoring apparatus 301 may take the form of an EEG monitoring device that includes EEG monitoring sensors, such as electrodes 305, which may contact the subject. In some embodiments, the electrodes 305 may be placed on the head for EEG monitoring.

As shown in FIG. 8, in another embodiment, a system 400 may include a monitoring apparatus 401 and a receiving station 410. In this embodiment, however, the monitoring apparatus 401 may include a headband 407, that incorporates electrodes 405, that is to be positioned in a noninvasive manner on the subject's head. As evident from FIGS. 7-8, the monitoring apparatus may include displays 330, 430. The displays may be configured to display the messages generated by the receiving stations and/or monitoring apparatuses.

In the embodiments of FIGS. 7-8, the displays 330, 430 may be configured such that they display a message that conveys data indicative of the subject's sleep status and the sleep disturbance priority. For example, the displays 330, 430 may include a message conveying that the subject is awake or asleep. The displays 330, 430 may also display the amount of time a subject has been asleep, such as illustrated on the areas indicated by reference lines 335, 435. Other data may also be included such as illustrated by the areas indicated by reference lines 337, 437. Examples of other data that may be included, including the disturbance events authorized for a particular patient during a particular disturbance priority, such as dictated by the rules explained herein above, the vitals of the patient, as measured, for example, by conventional means, and transmitted to the receiving stations, identifying information or other information about the subject. In some embodiments, the displays may display green to indicate that the subject is awake and that all disturbance events may be administered, and the display may likewise display red to indicate that the subject is asleep and only emergency disturbance priority events may be administered. A yellow designation on the display may also be used to indicate that intermediate priority events, as well as top level events, may be administered such as after the subject has a reached a predetermined period of sleep or stage of sleep. The display may also indicate whether the subject is transitioning to sleep.

In yet further embodiments, a non-audible alarm system may be used. In hospital settings, in particular, audible alarms, such as buzzing or beeping, are used to indicate to an operator, such as a nurse, that something needs to be addressed, such as medication needing to be replaced/refilled, vital measurements reaching prohibited limits, etc. However, a non-audibile alarm system may be used wherein an operator has a mobile device, such as a smart watch, smart phone, tablet, pager, or other mobile device, that can produce a non-audible alarm. What is meant by non-audible is non-audible by the subject so as not to disturb the subject more than is necessary. For example, the mobile device may vibrate, or an audible alarm remote from the subject, such as at a nurses' station, or on a remotely located operator's mobile device may be used. In some embodiments, when an alarm event occurs in a patient's room, a central control system (e.g., a central server or a cloud based processing system) is notified (e.g., via a Bluetooth® Internet Gateway connected to the alarm producing device or other communications protocol) of the alarm event and determines which mobile device(s) should be notified of the alarm event without the alarm actually sounding in the patient's room. The mobile devices can produce a non-audible notification, such as a vibration, in response to being notified of the alarm event. In some embodiments, the mobile devices can receive and display information indicating where the alarm event is occurring, a type of the alarm event, etc., and/or request input from the individual, such as an acknowledgement that he or she has been notified of the event. In another embodiment, multiple individuals or a hierarchy of individuals can be notified of the alarm event. For example, a second individual can be notified of the alarm event if a first individual fails to provide an acknowledgement thereto within a certain time period.

The above described embodiments, systems, and methods may be implemented on a variety of computing devices and systems, including mobile devices, such as smart phones and/or tablet computers, and/or server computers, wherein these computing devices include the appropriate processing mechanisms and computer-readable media for storing and executing computer-readable instructions, such as programming instructions, code, and the like. As shown in FIG. 9, computers 900, 944, in a computing system environment 902 are provided. This computing system environment 902 may include, but is not limited to, at least one computer 900 having certain components for appropriate operation, execution of code, and creation and communication of data. For example, the computer 900 includes a processing unit 904 (typically referred to as a central processing unit or CPU) that serves to execute computer-based instructions received in the appropriate data form and format. Further, this processing unit 904 may be in the form of multiple processors executing code in series, in parallel, or in any other manner for appropriate implementation of the computer-based instructions.

In order to facilitate appropriate data communication and processing information between the various components of the computer 900, a system bus 906 may be utilized. The system bus 906 may be any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, or a local bus using any of a variety of bus architectures. In particular, the system bus 906 facilitates data and information communication between the various components (whether internal or external to the computer 900) through a variety of interfaces, as discussed hereinafter.

The computer 900 may include a variety of discrete computer-readable media components. For example, this computer-readable media may include any media that can be accessed by the computer 900, such as volatile media, non-volatile media, removable media, non-removable media, etc. As a further example, this computer-readable media may include computer storage media, such as media implemented in any method or technology for storage of information, such as computer-readable instructions, data structures, program modules, or other data, random access memory (RAM), read only memory (ROM), electrically erasable programmable read only memory (EEPROM), flash memory, or other memory technology, CD-ROM, digital versatile disks (DVDs), or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage, or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the computer 900. Further, this computer-readable media may include communications media, such as computer-readable instructions, data structures, program modules, or other data in other transport mechanisms and include any information delivery media, wired media (such as a wired network and a direct-wired connection), and wireless media, such as Wi-Fi and/or Bluetooth® technology. Of course, combinations of any of the above should also be included within the scope of computer-readable media.

The computer 900 further includes a system memory 908 with computer storage media in the form of volatile and non-volatile memory, such as ROM and RAM. A basic input/output system (BIOS) with appropriate computer-based routines assists in transferring information between components within the computer 900 and is normally stored in ROM. The RAM portion of the system memory 908 typically contains data and program modules that are immediately accessible to or presently being operated on by processing unit 904, e.g., an operating system, application programming interfaces, application programs, program modules, program data, and other instruction-based computer-readable codes.

With continued reference to FIG. 9, the computer 900 may also include other removable or non-removable, volatile or non-volatile computer storage media products. For example, the computer 900 may include a non-removable memory interface 910 that communicates with and controls a hard disk drive 912, i.e., a non-removable, non-volatile magnetic medium; and a removable, non-volatile memory interface 914 that communicates with and controls a magnetic disk drive unit 916 (which reads from and writes to a removable, non-volatile magnetic disk 918), an optical disk drive unit 920 (which reads from and writes to a removable, non-volatile optical disk 922, such as a CD ROM), a universal serial bus (USB) port 921 for use in connection with a removable memory card, etc. However, it is envisioned that other removable or non-removable, volatile or non-volatile computer storage media can be used in the exemplary computing system environment 900, including, but not limited to, magnetic tape cassettes, DVDs, digital video tape, solid state RAM, solid state ROM, etc. These various removable or non-removable, volatile or non-volatile magnetic media are in communication with the processing unit 904 and other components of the computer 900 via the system bus 906. The drives and their associated computer storage media discussed above and illustrated in FIG. 9 provide storage of operating systems, computer-readable instructions, application programs, data structures, program modules, program data, and other instruction-based computer-readable code for the computer 900 (whether duplicative or not of this information and data in the system memory 908).

A user may enter commands, information, and data into the computer 900 through certain attachable or operable input devices, such as a keyboard 924, a mouse 926, a touchscreen, etc., via a user input interface 928. Of course, a variety of such input devices may be utilized, e.g., a microphone, a trackball, a joystick, a touchpad, a touch-screen, a scanner, etc., including any arrangement that facilitates the input of data, and information to the computer 900 from an outside source. As discussed, these and other input devices are often connected to the processing unit 904 through the user input interface 928 coupled to the system bus 906, but may be connected by other interface and bus structures, such as a parallel port, game port, or a USB. Still further, data and information can be presented or provided to a user in an intelligible form or format through certain output devices, such as a monitor 930 (to visually display this information and data in electronic form), a printer 932 (to physically display this information and data in print form), a speaker 934 (to audibly present this information and data in audible form), etc. All of these devices are in communication with the computer 900 through an output interface 936 coupled to the system bus 906. It is envisioned that any such peripheral output devices can be used to provide information and data to the user.

The computer 900 may operate in a network environment 938 through the use of a communications device 940, which is integral to the computer or remote therefrom. This communications device 940 is operable by and in communication to the other components of the computer 900 through a communications interface 942. Using such an arrangement, the computer 900 may connect with or otherwise communicate with one or more remote computers, such as a remote computer 944, which may be a personal computer, a smart phone, a tablet computer, a server, a router, a network personal computer, a peer device, or other common network nodes, and typically includes many or all of the components described above in connection with the computer 900. Using appropriate communication devices 940, e.g., a modem, a network interface or adapter, etc., the computer 900 may operate within and communicate through a local area network (LAN) and a wide area network (WAN), but may also include other networks such as a virtual private network (VPN), an office network, an enterprise network, an intranet, the Internet, etc. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers 900, 944 may be used.
